Dublin Archbishop Diarmuid Martin retires Archbishop of Dublin Diarmuid Martin (Niall Carson/PA) Pope Francis has accepted the resignation of Dublin Archbishop Diarmuid Martin, who worked to rebuild the Roman Catholic Church’s credibility in Ireland after it was shattered by decades of clerical sexual abuse and cover-up. Archbishop Martin turned 75 earlier this year, the mandatory retirement age for bishops. Francis named Bishop Dermot Farrell, 66, the head of the Ossory diocese in eastern Ireland, as Archbishop Martin’s replacement. Deeply Catholic Ireland has had one of the world’s worst records of clerical sex abuse, crimes that were revealed to its 4.8 million people over the past decade by a series of government-mandated inquiries.
